The KNS Precision Compact AR/MCX Stock Adapter gives you a modular solution for streamlining your rifle platform. Whether you're running a direct impingement AR-15, piston gun, or SIG MCX, this compact adapter lets you standardize your ergonomics and maintenance across different platforms—a smart move if you're rotating between builds or want consistent controls in a fight or at the range.
Built with KNS's reputation for precision engineering, this adapter is designed to fit tight spaces and support various stock configurations. It's the kind of no-nonsense component that works in the background, which means it has to work reliably every time.
If you're building a rifle chambered in 5.56, .300 Blackout, or another AR-compatible caliber, or setting up an MCX platform, this adapter bridges the gap between your lower receiver and your choice of stock. It's ideal for operators who value modularity and want to keep their setup flexible without sacrificing fit or function.
